An Arduino developer has committed a fix for the TCP server hang-up issue! You'll have to grab it off of github and flash your shield. I haven't tested it yet, but I'll flash it in a couple hours and update this thread.Issue #9: Connection dies after a few seconds · arduino/wifishield@241730e · GitHub
I still experience the server timeout issue after flashing this. A keep alive using server.write("\0") works though.
